Does anyone know of a resource that can tell you the airspace based on US address? The b4UFly app does not work for Part 107 pilots. It seems to be targeted at hobbyists. I tried AirMap, but it does not include accurate up to date Class E surface area information needed for UAS pilots restricted by Part 107. Is there a way to superimpose satellite imagery on sectionals at SkyVector? Any other resources out there I'm missing? There are lots of areas I need to operate near these Class E extensions to Class D and I would rather not ask for authorization or waiver if not necessary. I noticed today the DJI GO app mistakenly said I was in a Class E area, which I know to be false. When near the edge I just want to be sure.
